commit b4f17a488ae2e09bfcf95c0e0b4219c246f1116a upstream. While reading the config parsing code I noticed this check is missing, without this check config->desc.wTotalLength can end up with a value larger then the dev->rawdescriptors length for the config, and when userspace then tries to get the rawdescriptors bad things may happen.
